luckyBackup is a powerful, fast, reliable, and fully customizable backup and sync tool. It can backup any directory (the source) to another (the destination). luckyBackup copies over only the changes you've made to the source directory and nothing more, saving a great deal of time for backups after the first one. Whatever changes you make to the source, including adding, moving, deleting, modifying files or directories, will have the same effect on the destination. Owner, group, time stamps, links, and permissions of files are preserved (unless directed otherwise). The synchronization feature works on any pair of directories, keeping the files that were most recently modified on both of them. It includes many safety checks to prevent accidental loss of data.

Fish Sync is a file syncing application. It can transfer multiple folders between multiple machines, keeping these folders synchronized. The Fish package does not need to be available on each machine in the group, only on the machine initiating the synchronization. The Fish program is separated into two pieces, one which does the work in the background, and the other a frontend configuration tool. This separation allows the Fish service to be run on servers where a GUI interface is not desired.
